Natural History:

I have relatively few observations of this species. At La Selva Biological Station, it occurred in only 1 of 51 Project ALAS fogging samples, but I collected it by hand twice in tree canopies, once in a Pentaclethra and once in a Terminalia. I also collected it in a Winkler sample of forest floor leaf litter from Hitoy Cerere. I collected a nest in the Santa Marta area of Colombia, in a 9mm diameter dead stick.

This concept of longicornis matched Panamanian specimens sent to me by Ralph Saporito, and reported in a study of alkaloidal toxins of dendrobatid frogs (Saporito et al. 2004).
